Mellingers sells a jiffy 4inch round (25 or more) for $.105 each or (500 or more) for $.08 each. The item number is 340 and their phone number is 1-800-321-7444. The downside is the shipping is pretty expensive between $5.20-12.50 for 1-20lbs. If you have some time I would request a cataloge has they have quite a bit of neat stuff. Mr Fool
